AIX upgrade

i upgrade aix ml 5.3.2.1 to 5.3.2.2 but when running commnd #oslevel -r
shows out put, again 5.3.2.1-- where should i chek???

2-can any one tell me when mknfs command run which files get updated??

my proposition use man: man oslevel, man mknfs
1)

oslevel-f

2)

man mknfs

OK
we can read
mknfs can change file:
/etc/inittab
to execute the /etc/rc.nfs on the system start,
or starts the /etc/rc.nfs file to start NFS imediately

1) You can issue a:

instfix -i| grep ML

.. and have a look what might be missing.

2) See john1212 answer or type in

man mknfs

and read the description.
